MECHANlCAL MOTOR.

SPECIFICATION forming part of Letters Patent No. 307,853, dated November11, 1884.

Application filed August 28, 1884.

T0 aZZ whom it may concern.-

Be it known that I, ISAAC N. GRovEs, a citizen of the United States,residing at Clio, in the county of Brown and State of Texas, haveinvented certain new and useful Improvements in Mechanical Motors, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

My invention has relation to mechanical motors, and its object is toconvert a given r0- tary into a vertical reciprocating motion, and toprovide means whereby the stroke of the reciprocating motion may beincreased or diminished, .according to the use or work to which themachine may be applied; and to these ends the novelty consists in theconstruction, combination, and arrangement of the same, as will behereinafter more fully described, and particularly pointed out in theclaim. I

The figure in the drawing is a perspective elevation of my improvedmotor.

A A are the sides, provided with legs a, which constitute the frameworkof the machine. B is the main driving-shaft, having crank b foroperating the same. 0 is a gearwheel centrally secured to said shaft, soas to mesh with the pinion D, secured toa secondary shaft, (not shown-,)on the outer end of which is a faceplate, E, having crank-pin holes 0(No model.)

located at different distances from the center. F is a removable screwcrank'pin, which engages the lower end of the pitman G, its up per endbeing attached to the rear end of the lever H. This lever is fulcrumedin the adjustable standard I, and its forward end, i, is bifurcated toreceive the end of the reciprocating bar K, which works in a guide, 12,in the arm N, secured to the frame. A The lever H is provided with aseries of fulcrum-holes, h, by means of which the stroke of the endt'maybe increased or diminished as the lever is adjusted, and the standard Imay be adjusted to one of the series of holes 0 in the frame, so as toobtain greater or less power on the lever.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent of the United States, is-

The combination, with the frame A, shaft B, gear 0, pinion D, faceplateE, and pitman G, of the adjustable lever H 0, standard I, and thereciprocating bar K, working in the guidearm a N, constructed andarranged substantially as and for the purpose set forth.

In testimony whereof I affix my signature in 55 presence of twowitnesses.

ISAAC N. GROVES.
